Abstract

remoção biológica anóxica simultânea de fósforo e de nitrogênio com recuperação de energia. a presente invenção refere-se a métodos e a sistemas para tratar água servida para simultaneamente remover nitrogênio, carbono e fósforo, embora recuperando energia na forma de metano e dióxido de carbono. uma corrente contendo amônia é direcionada para um tanque de pré-tratamento que produz lodo em excesso, biogás e corrente pré-tratada. a corrente pré-tratada tem pelo menos 45% menos de carbono do que a corrente contendo amônia. a corrente pré-tratada é então direcionada para um tanque anóxico, que promove liberação de fósforo e a fermentação de matéria orgânica particulada e dissolvida. o liquor misturado é transferido para um tanque aerado tendo baixas concentrações de oxigênio dissolvido para promover o desenvolvimento de bactérias de fósforo que são eventualmente recicladas para o tanque anóxico por intermédio do retorno de lodo ativado. simultaneamente ocorre nitrificação, desnitrificação e liberação de fósforo no tanque aerado. um tanque de membrana separa o efluente tratado do lodo ativado em um tanque de membrana.Simultaneous anoxic biological removal of phosphorus and nitrogen with energy recovery. The present invention relates to methods and systems for treating wastewater to simultaneously remove nitrogen, carbon and phosphorus while recovering energy in the form of methane and carbon dioxide. A stream containing ammonia is directed to a pretreatment tank that produces excess sludge, biogas, and pretreated stream. The pretreated stream has at least 45% less carbon than the ammonia-containing stream. The pretreated stream is then directed to an anoxic tank, which promotes phosphorus release and the fermentation of dissolved and particulate organic matter. The mixed liquor is transferred to an aerated tank having low dissolved oxygen concentrations to promote the development of phosphorus bacteria which are eventually recycled to the anoxic tank by the return of activated sludge. At the same time nitrification, denitrification and phosphorus release occur in the aerated tank. A membrane tank separates treated effluent from activated sludge into a membrane tank.
